12V Regulated DC Power Supply (AC-DC)

A reliable and high-safety 12V DC power supply designed to convert AC input (from a transformer) into a stable DC output. This project emphasizes industrial safety standards with a focus on high-voltage isolation and thermal stability.

🛠 Hardware Specifications

PCB Type: Single Sided (Bottom Layer) with Top Silkscreen.
Board Dimensions: 124 mm x 91 mm.
Safety Feature: 18 mm clearance between AC primary and DC secondary sections.
Thermal Management: Dedicated M3 mounting hole for a TO-220 heatsink.
